LASER LINES FROM CO₂ IN THE 11–18 MICRON REGION

Abstract

A number of lines at 11 microns emitted from a pulsed CO 2 laser have been identified as the P branch of the CO 2 vibrational transition (01 1 1)–(11 1 0). Five other transitions, between 13 and 18 microns, have been observed. The possibilities that these are perpendicular transitions with Δν 2 = 1 are discussed.
